l No. 892,502.

To all whom 'it may concern."

Be it known that I, JAMES SAMUEL CooN,

a citizen of the'United States, residing at 'tion whereby corn and other grain maybe thoroughly dried and cleaned without the employment of expensive machinery.

further object of the invention is to provide a cleaning and drying means which may be readily attached to an elevator or other building where gram is stored 'and used for the plur ose offA cleaning and drying the grain ast e atter is delivered to cars or other points..

' A still further object of the invention is to provide a cleaner and drier that may be placed outside the building in order not to occupy valuable room, and at the same time to expose the grain tothe action of light and air. l

these and other objects inview, as willlmore'fully hereinafter appear, the invention conslsts 1n certain nove features of construction and arran ement of parts, hereinafter fully describe illustrated in the accompanying drawings, and particularlypoint- -ed out in the appended claims, it being understood that various changes inthe form, proportlons, size and minor details of the .structure may be made without departing from the s irit or sacrificing any of the advanta es o the invention.

In t e accompanying drawings:-Figure 1s a vertical section o a grain cleaner and drier constructed and arranged in accordance with the invention. Fig. 2 is a sectional plan view of t'he same on the line 2-2 of Fig. 1, the view being on an enlar ed scale. Fig. 3 is a vertical section of the dlstributing hopper on the line3-3 of Fig. 1. Fig. 4 is a vertical section showing a modiicationof the drying cylinder. Fig. 5 is a sectional plan view -of the same.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings. L.

building is a vertically disposed screen 10 which referably extends for the full height of the lliuilding and which may be supported atv intervals by brackets or other carriers. Extending centrally through this cylinder is a stationar shaft or spindle on which is mounted a elically wound metallic sheet 12 extendin from the spindle to the inner wall ofthe cy inder and provided with numerous perforations topermit the free circulationof air.

The cylinder is arranged outside the building, so that it ma be exposed to the action of Sun and air, an to the rear ofthe cylinder 'is a reflector 15 of concaved form in cross section and mounted onV collars so that it may be swung from side to side for the purpose of reflecting sun rays on to the cylinder.

Arranged'at t e rear of the cylinder is a series of superposedfan casings 16 of cylindrical form an which communicate with the cylinder through vertical] isposed passages 17 that are practical y continuous in length, and through which currents of air are forced by fans 18 that are carried by a shaft 1 9 dis osed at the center of the cy ders 16. T e shaft is continuous and carries the' entire series of Jfans, while at its lower end is secured a pulley which may be driven by a belt 20 from any suitable source of power.

Arranged in the upper portion of the building below the distributing spout 20 of an elevator head 21 is a ho per shaped casing 22 in the vu per fportion ci) which are arranged a plura ity o spreading or delecting plates 23 which serve to divide and s read the stream of ain, so that it will fa in acorn arative y thin stream for the full width o the casing. Leading from this casing-is the in-.

duction tube 24 of a suction fan 25 having an outlet 26 that leads to the dust house, and at the juncture of the upper wall of the induction tube with the 'casing is a deflector plate 27 which serves to prevent the passage of grain into the fan.

The stream of grain falls from the bottom of the casing into a collectinvhopper 28, the 4top of which is open, so that air will be drawn down through the top of the hopper and up through the bottom of the casing, passing through the stream of falling gram and serving to dry the grain, and at the saine time to carry away dust, sillas, husks,

chaff and other foreign. material, this mate-l rial assing through the induction tube of the evice and thence through the fan and tube 26 to the dust house.

Leading Jfrom the hopper 28 is an inclined chute 31 having a solid bottom and provided with a foraminous to orJ cover 32. The grain passes through t is chute to a point outside the building and through a vertical pipe 33 from whence it is delivered into the upper portion of the cylinder 10, the grain flowing down through the helical chute within the cylinder. y

rlhe grain-slides slowly down and around the helical chute, and will be agitated in such manner that all portions will be exposed to the action of sun and air, so that by the time the grain reaches the bottom or delivery chute 35, it will be thoroughly cleaned anddried and its value materially increased.

lt will be seen that the cleaner and drier needs practically no machinery, the only operating part being the fan or blower which lis actuated Jfrom the elevator, and the fan` which is placed at the side of vthe vertical cylinder outside the building,

thermore being arranged outside the building l will not occupy valuable storage s ace.

lt is obvious that the drying cy mder may be made ofrectangular form in cross section, as shown in Fig. 4, and* rovided with shelves 40 arranged alternate y in op osite directions, so that the grain will flow om shelf to The device furshelf, and thus be subjected to the action of the air and sunlight. y v
